“…R. mucilaginosa were isolated in several laboratories, mostly from the oral cavity, throat, dental plaques, and persistent apical periodontitis (Gordon, 1967;Pinsky et al, 1989;Rubin et al, 1978;Bowden, 1969;Yamane et al, 2010). Furthermore, the organism is responsible for a variety of opportunistic infections (Pinsky et al, 1989;Lemozy et al, 1990;Magee et al, 1990;Mitchell et al, 1990;Abraham et al, 1997). Immunocompromised patients are often infected with this pathogen, leading to endocarditis (Pinsky et al, 1989;Rubin et al, 1978;Mitchell et al, 1990;Coudron et al, 1987), sepsis (Barlow et al, 1986;Poirier and Gaudereau, 1989), and peritonitis (Mitchell et al, 1990).…”
